Answer: The orientation of the vertices was changed.
(x, y) ---> (x + 8, y - 3)
Step-by-step explanation: The triangle translation isn't on quadrant II, it's on quadrant I, so that answer choice isn't correct. The triangle ABC translated 8 units right and 3 units down, not 8 units left and 3 units up. Whenever you dilate, translate, rotate, or reflect triangles like ABC, the next triangle becomes A'B'C because it shows you that it's a transformation of the original triangle. The orientation of the figure didn't change, because it didn't change shape, rotation, or size, so the orientation wasn't affected at all, just the vertices.
The transformation is (x, y) ---> (x + 8, y - 3), because think of it like this. I already said that the triangle translated 8 units to the right, which means that the triangle is translating 8 units in the positive direction to the right. The triangle going 3 units down is in the negative direction, and that's why it's (x, y) ---> (x + 8, y -3).
Let me know if this is right! :)

Answer:
161
Step-by-step explanation:
It's a system of equations, let's solve it step-by-step!
Equation: [3 * 2^5 + 13 * (-2)] + 7[8 - (4 - 9)]
2^5 = 32
so we have [3 * 32 + 13 * (-2)] + 7[8 - (4 - 9)].
3 * 32 = 96
so we have [96 + 13 * (-2)] + 7[8 - (4 - 9)].
13 * (-2) = -26
so we have [96 - 26] + 7[8 - (4 - 9)].
96 - 26 = 70
so we have 70 + 7[8 - (4 - 9)].
4 - 9 = -5
so we have 70 + 7[8 - (-5)].
8 - (-5) = 13 (the signs cancel out)
so we have 70 + 7[13].
7 * 13 = 91
so we have 70 + 91.
70 + 91 = 161
Therefore our answer is 161.

How to get rid of a square root in the denominator?.
Step-by-step explanation:
you multiply both the top and bottom by the root if it was alone.
let's say if we had (1 - sqrt(2)) in the denominator. here we multiply both the numerator and the denominator by the conjugate.
the conjugate is formed by changing the sign between two terms in a binomial. so in this case the conjugate is
(sqrt(2) -1)

The radius of a circle is 7 m. Find its circumference in terms of
π
π.
[tex]circumference = 2 \times \pi \times r[/tex]
[tex]circumference = 2 \times \pi \times 7[/tex]
[tex]circumference = 14\pi[/tex]
Answer:
14π
Step-by-step explanation:
Given:
Radius of circle = 7 mTo determine the circumference of the circle, we need to use the formula 2πr, where "r" represents the radius of the circle.
Substitute the radius in the formula:
[tex]\implies 2\pi (r) = \text{Circumference}[/tex]
[tex]\implies 2\pi (7) = \text{Circumference}[/tex]
Simplify the circumference:
[tex]\implies 2\pi (7) = \text{Circumference}[/tex]
[tex]\implies 14\pi = \text{Circumference}[/tex]
Thus, the circumference is 14π.

WILL GIVE BRAINLIEST (08.03) Consider the following pair of equations:
y = 3x + 3
y = x − 1
Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form.
Answer:
(- 2, - 3 )
Step-by-step explanation:
y = 3x + 3 → (1)
y = x - 1 → (2)
substitute y = 3x + 3 into (2)
3x + 3 = x - 1 ( subtract x from both sides )
2x + 3 = - 1 ( subtract 3 from both sides )
2x = - 4 ( divide both sides by 2 )
x = - 2
substitute x = - 2 into either of the 2 equations and evaluate for y
substituting into (2)
y = - 2 - 1 = - 3
solution is (- 2, - 3 )
Answer:
y = -3, x = -2
Step-by-step explanation:
1. Substitute "y = x - 1" in for y in the first equation:
x - 1 = 3x + 3
2. Isolate x:
x = 3x + 3 + 1
3. Combine like terms:
-2x = 4
4. Solve for x:
-2x/-2 = 4/-2
x = -2
5. Solve for y with substitution (using the second equation):
y = -2 - 1
y = -3

The graph that represents the solution set for x > -6 is Graph D.
What is Number line?In mathematics, a number line is a straight line that represents numbers and their relative positions. It is a visual representation of the real number system.
To find the solution set for the inequality 2x + 3 > -9,
2x + 3 > -9
Subtract 3 from both sides:
2x > -12
Divide both sides by 2:
x > -6
The solution set for the inequality is x > -6, which means that x is greater than -6.
So, Among the given graphs, the graph that represents the solution set for x > -6 is Graph D.

A student uses the equation tangent theta = startfraction s squared over 49 endfraction to represent the speed, s, in feet per second, of a toy car driving around a circular track having an angle of incline theta, where sine theta = one-half. to solve the problem, the student used the given value of sine theta to find the value of tangent theta and then substituted the value of tangent theta in the equation above to solve for s. what is the approximate value of s, the speed of the car in feet per second? 5.3 7.5 9.2 28.3
The approximate value of the speed of the car in feet per second is A. 5.32 ft/s.
How to find the spped?An equation is an expression that shows the relationship between two or more numbers and variables. In this case, tan(θ) = s² / 49
sinθ = 1/2
θ = sin⁻¹ (0.5) = 30⁰
tan(30) = s² / 49
s = 5.32 ft/s
Therefore, the approximate value of the speed of the car in feet per second is 5.32 ft/s.

Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target.
We can try for loops along with conditional statements to get the indices of the needed numbers.
What is zero-based indexing?Zero-based indexing indexes the elements of an array or such container starting from 0, instead of starting from 1 (which is what we usually do in real life).
For this case, assuming we want to write code in python, and array being simple list, plus we want the index of only first two numbers found which add up to the target, we have:
for idx_1 in range(len(arr)//2 + 2):
num_1 = arr[idx_1]
found = 0
for idx_2 in range(idx_1 + 1, len(arr)):
num_2 = arr[idx_2]
if target == num_1 + num_2:
print(idx_1, idx_2)
found = 1
break
if found: break
Here we used 'range' function for first loop, which defaulty generates integers from 0, but can generate integers from whatever integer. Like in the second loop, it generates number from idx_1 + 1. Also, it doesn't include the last integer, given by the upper limit for the range.
This python code gives the indices of a pair of two numbers from the array given which adds up to the target.
Thus, we can try for loops along with conditional statements to get the indices of the needed numbers.

A bus travels 25 yards in 1 second. How many miles will it travel in 2 hours?
Answer:
102 miles
Step-by-step explanation:
In 2 hours there are 7200 seconds ([tex]60*60 = 3600 * 2 = 7200[/tex])
In one second the bus travels 25 yards, so; [tex]7200 * 25 = 180,000 yards[/tex]
Converting yards to miles is: [tex]x (yards) / 1760[/tex]
[tex]180000/1760 = 102.2727272...[/tex]
